Istio features and specs

  • Traffic Management
    Istio provides powerful traffic management capabilities, including fine-grained control over the flow of traffic and API calls between services.
  • Observability
    Istio enhances observability with metrics, logs, and tracing, making it easier to monitor microservices and gain insights into performance and behavior.
  • Security
    Istio improves security by providing service-to-service and end-user authentication, as well as powerful policy enforcement for access control.
  • Policy Enforcement
    Istio allows for the enforcement of organizational policy and access control, making it easier to ensure compliance and governance.
  • Service Resilience
    Capabilities such as circuit breakers, retries, and timeouts make applications more resilient to failures and ensure greater availability.
  • Platform Agnostic
    Istio is designed to be platform agnostic and can be deployed on any Kubernetes platform, making it highly flexible.

Possible disadvantages of Istio

  • Complexity
    Istio adds a significant amount of complexity to a system, which can make it harder to manage, especially for teams without experience in service meshes.
  • Resource Consumption
    Istio can be resource-intensive, requiring additional CPU, memory, and storage, which can lead to higher operational costs.
  • Learning Curve
    There is a steep learning curve associated with Istio, making it challenging for new users to get up to speed quickly.
  • Operational Overhead
    Managing and operating Istio might require dedicated personnel and can introduce operational overhead, including the need for monitoring and updating the control plane and sidecar proxies.
  • Latency
    The addition of sidecar proxies and other Istio components can introduce some latency in the network traffic between services.

Azure Application Gateway features and specs

  • Scalability
    Azure Application Gateway can automatically scale up or down based on traffic demands, ensuring application availability and performance without manual intervention.
  • Security Features
    It offers a Web Application Firewall (WAF) that helps protect your applications from common vulnerabilities and attacks, improving the overall security posture.
  • SSL Termination
    By offloading SSL termination to the application gateway, it reduces the web server's computation load, allowing better resource allocation.
  • URL-based Routing
    Supports URL-based routing which allows for more advanced traffic distribution strategies and optimization of backend resources.
  • Multi-Region Redundancy
    Supports configurations for multi-region redundancy, allowing for improved resilience and availability across geographical locations.

Possible disadvantages of Azure Application Gateway

  • Complexity
    Initial setup and configuration can be complex, especially for users who are not familiar with Azure services, potentially leading to increased deployment times.
  • Cost
    Costs can increase significantly with higher traffic volumes and additional features like the Web Application Firewall, impacting the overall IT budget.
  • Latency
    There might be additional latency introduced due to the routing and processing of requests through the gateway, which can affect application performance.
  • Limited Customization
    Compared to some other solutions, Azure Application Gateway offers limited customization options for specific routing and traffic management scenarios.
  • Dependency on Azure Region
    Performance and availability can be impacted by the Azure region where the application gateway is deployed, leading to potential issues if that region experiences problems.

  • Evaluating 2 Popular Service Meshes
    The decision to add a Service Mesh to an application comes down to how your application communicates between itself. If for instance your design is heavily asynchronous and relies on events and messages, then a service mesh isn't going to make a lot of sense. If however, you've built an application that is heavily reliant on APIs between itself, then a service mesh is a great piece of technology that can make this... - Source: dev.to / 7 months ago
  • Kubernetes Multi-Cloud Multi-Cluster Strategy Overview
    Istio: Istio is one of the leading Kubernetes service mesh solutions. You can use Istio to set up multi-cluster networking, allowing workloads in one cluster to interact with those in other clusters. This gives you more flexibility in where and how you deploy your apps. - Source: dev.to / 7 months ago
  • Using Istio Resources with nxs-universal-chart
    Istio is an open-source project that handles routing problems arising in microservices-based applications. - Source: dev.to / 9 months ago
  • 26 Top Kubernetes Tools
    Istio is a service mesh that enables simpler networking, traffic management, service discovery, and monitoring for your Kubernetes clusters. It coordinates communications between your app's microservices, providing much more control than the plain Kubernetes Service model. - Source: dev.to / 11 months ago
  • eBPF, sidecars, and the future of the service mesh
    Bart: You raise a crucial point about the human aspect. While we address technical challenges, the time spent resolving errors detracts from other tasks. The community has developed products and projects to tackle these concerns and costs. One such example is Istio with Ambient Mesh. Another approach is sidecarless service meshes like Cilium Cluster Mesh. Can you explain what Ambient Mesh is and how it enhances... - Source: dev.to / 12 months ago

  • Free and Built-In TLS/SSL certificates in Azure
    It should be easy and free to enable SSL/TSL certificates in Azure. This was the number one question on UserVoice feedback. Microsoft implemented this Built-In free certificate option for some services, like Azure CDN, Front Door, Application Gateway, etc. When you put one of those services in front of your web site (like what I did with this blog), you can enable an auto-renewable Built-In certificate for free. - Source: dev.to / about 4 years ago
